YARN PACKAGE AND THE LIKE AN D METHOD AND MECHANISM FOR WINDING IT.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed April 14, 1920. Serial No. 373,950.

To all whom it may concern Be it known that I, THOMAS ANDREW, a subjectof the King of the United Kingdom of Great Britain and Ireland, andresident of 492 Manchester road, Rochdale, in the county of Lancaster,England, have invented new and useful Improvements in Yarn Packages andthe like and Methods and Mechanism for Winding Them, of which thefollowing is a specification.

The object of this invention is to make more easy, convenient andexpeditious than it has hitherto been the attachment of the last woundend of the yarn of one yarn package to the first wound end of anotherfor the placing of yarn packages one after another in creels with thebeginning of each attached to the end of another and the continuousrunning oil or unwinding of one yarn package after another. To this end,the invention consists in a method and means for winding yarn packages,which are provided with securely fixed coils wound on the yarn holders,previously to the ordinary windings or coils at the first wound portionsof the formation in ring spinning machines, ring doubling machines andother machines having ring rails or other yarn guiding means moved likering rails.

In the accompanying drawings Figure 1 is a diagrammatic side elevationof the lower part of a bobbin with yarn wound upon it below andpreviously to the ordinary windings forming the bottom of the bobbin andFigs. 2 and 3 are respectively a side elevation and a transverse sectionof a portion of a ring spinning machine suflicient for the illustrationof the mecha nism provided according to this invention. Fig. 4 is adetail of the sector and its adjacent mechanism.

Fig. 1 shows an end 1 of yarn led to the yarn holder, as secured inposition by a downwardly wound coil 3 being first wound on the yarnholder 2 and then an upwardly wound coil 4 being wound over it and theend 5 of yarn extending from the upwardly wound coil 4 being led to andwound in the bottom 6 of the ordinary windings of yarn on the yarnholder 2. By a suitable number of turns being included in the downwardly and upwardly wound coils 3 and 4 any length of yarn requisite maybe pro vided for facilitating the connection of the end first wound uponone yarn holder to the end last wound'upon another in order that theyarn holders may be mounted in creels and unwound successively in themanner hereinbefore mentioned. By the ends 1 and 5 of yarn being securedrespectively by the coils 3, 4 and by the ordinary windof the bottom 6of the yarn package on the yarn holder 2, the coils 3, 4 are themselvessecured in position on the yarn holder 2 so that the end 1 is kept inposition to be found easily and the length of yarn for the connection ofone yarn package to another is retained on the yarn holder 2 andpreserved from unwinding or breakage in the handling or carriage of theyarn packages until required for use.

Coils or windings of opposite hand are wound one to overlap another on.yarn holders previously to the commencement of the coils or windings ofthe bottoms or like parts of yarn packages, such as bobbins, so as to beon parts of the yarn holders to project fromthe completed yarn packagesat the ends at which winding was begun, so that the earlier wound coilor winding secures the end of yarn first led tothe yarn holder and isitself securedby a later coil or winding of opposite hand and the lastoverlapping coil is secured by the yarn forming its end portionextending into the bottom or likebasal part of the age.

The winding of the coils or windings of opposite hand on portions ofyarn holders to project from the ends of yarn packages where the windingthereof begins may advantageously be eii'ected after empty yarn packageshave been applied to spindles on which coils or windings have been woundin the ordinary way preparatory to'the deifyarn packmg or removal ofcompleted yarn packages.

Further according as an example of the way of carrying it into effect,the usual device which is movable for lowering a ring rail in orderthatyarn may be wound on spindles below the bottoms of yarn packages, isemployed and made to occupy for a short time prior to the commencementof the bottoms or'like parts of yarn packages, a position intermediatebetween that in which windings on ,the spindles below the yarn holdersis eiiected and the position occupied by it for winding of yarnpackages.

As shown in Figs. 2 and 3, the usual toothed sector 7 with a pulley 8guiding a chain 9 used in working the ring rail 10 to this invention andyarn packages are and movable into one position for winding of yarn ontoyarn holders in the winding or formation of yarn packages in theordinary way and into another position for yarn to be wound on spindlesbelow the bottoms 6 of yarn holders in preparation for the removal ofcompleted yarn packages, is contrived to be put for a time in anintermediate position for yarn to be wound on the yarn holders belowwhere the bottoms 6 of to be formed in the ordinary working of the ringrail 10.

To. enable the sector 7 to be put into the intermediate position it isprovided with a dog or projection 12 with two places 13, 14 forengagement with the catch 15 which serves ordinarily for holding thesector 7 in position for the winding to proceed in the ordinary way. 7 r

The catch 15 is shown as a pivoted lever with a second arm 16 to arriveon the bracket 7 or part 17 on which the catch 15 is mountbeing woundtoo high.

ed and so to prevent the catch 15 from escaping from the dog orprojection 12 by movement in the direction indicated by; the arrow 18.The catch 15 is shown asprojecting rearwardly in Fig. 2 as a, hook toact as a stop for a projection 20 formed on the sector 7 so as toprevent such sector 7 from When the sector 7 is-in an intermediateposition it is preferable that the cam 21 for efi'ecting the upward anddownward movement of the ring rail10 should be brought to rest in a:desired position such that in -further movement it will first lower andthen raise the ring rail 10. Forthis to be done in the case illustrated,the cam 21 is provided with a striking part 22 shown as a stud orprojection in a suitable position'and a lever 23, with a treadle 24 anda. projection 25 preterably adjustable, which by "depression of thetreadle 24 can be brought into the path ofthe-striking'part 22, isconnected by a rod 26 to a lever 27 made'so to work an engageable anddisengageable clutch 28 ordinarily serving to transmit motion to the cam21 that when the treadle 24 is depressed rail 10. V

the clutch 28 is disengaged to allow the cam 21 to be moved to theposition intended by its, own weight or the weight of the ring A spring29 for engaging the clutch 28 and raising the treadle 24 is connected tothe lever 27 and the adjacent side frame of the machine. 7

In the case illustrated a shaft 30 and bevel wheels 31, 32 are used todrive the cam 31 and the clutch 28 is used for effecting con-.

nection and disconnection of the shaft 30 with and from the worm wheel33 and worm' V 34 for driving it. It will be seen from the drawings thatthe cam '21 works the ring rail 10 in the ordinary way by means of thebowl 35, 36,'barrel 37 and chain 38 and 10 for the cam 21 to cause yarnto be wound V on'the spindles below the bottoms of yarn holders 2 in theordinary way.

When the catch 15 ismade to bear against V the surface 13 of the dog orprojection 12, the sector 7 and pulley'8 are held in position forthe'cam 21 to wind yarn upon the yarn holders 2 in the ordinary way atthe bottom thereof and higher thereon according as the chain 9 isunwound from or wound less or more onto the barrel 37. The surface 14 onthe dog or projection 12 is formed a little higher than the surface 13,consequently when the chain 9 is wound off the barrel 37 engagement ofthe catch 15 with the surface 14 will enable the cam 21 to bring aboutmovement 01": the ring rail 10 for winding yarn upon the yarn holders 2below the place at which the'ordinary bottoms of yarn packages areeventually formed.

The stud 22 is fixed in such position in the wheel 32 fast with the cam21 that when the treadle 24 is depressed to disengage the clutch 28 andso to allow the cam 21 to be turned in the direction indicated by thearrow 41 by the weight of the ring rail 10 causing the bowl 35 to bearupon the are 43, 44 of the cam 21 between the part 42 of largest radiusand the part. 44 of smallest radius the striking part 22 comes againstthe pro jection 25 while the cam 21 has still to present the part 44 ofleast radius to the bowl 35. By this means when the clutch 28 is againallowed to pass into engagement by release of the treadle 24 the cam 21being again turned by the worm 34 and worm wheel 33 will first lower andthen raise the ring rail 10., V

In the use of the mechanism illustrated in the accompanying drawingswhen the windthe bottoms of the yarn holders so as to be fastened to thespindles 11. Then the com 'pleted or full yarn holders having been removed from the f spindles 11, empty yarn holders 2 are applied to thespindles 11. Then the handle 40' is turned to raise the sec tor 7 untilthe catch 15 can be engaged-with the surface 14 of the dog or projection12.

Then while the catch 15 is engaged with the surface 14, it isascertained by the observation of the position of the ring rail 10 orthe position of the cam 21 or the bowl 35 that the are 42, 43, 44 ispresenting to the bowl 35 a part between the part 42 of largest diameterand the part 43 to be against the bowl 35 when the stud 22 comes againstthe striking part 20. The treadle 24 is then depressed and held sodepressed until the cam 21 has brought the striking part 22 against theprojection 25 and then the treadle 24 is released so that the clutch 28may become engaged again. Then the ring spinning machine is started andas the spindles 11 begin to revolve, the cam 21 first lowers and thenraises the ring rail 10 so as to wind yarn first in a descending spiraland then in an ascending spiral on the yarn holders 2 below the place atwhich the ordinary bottoms 6 of the yarn packages will eventually bewound. Then the handle 40 is turned again to raise the sector 7 and thecatch 15 is brought into engagement with the surface 13 01": the dog orprojection 12 and the formation of the ordinary bottoms 6 of the yarnpackages on the yarn holders 2 and the rest of the winding of yarnthereon proceeds in the ordinary way.

When a ring spinning machine is first being put to work the roving to betwisted into yarn may be brought into connection with the spindles orthe yarn holders as in the ordinary way of first putting such a machineto work and the commencement of winding of yarn below the place at whichthe windings to form the bottoms of yarn packages are to be wound onyarn holders may then proceed as in the manner hereinbefore described.

If in any case there is no provision or occasion for yarn to be wound onspindles below the bottoms of yarn holders thereon, yarn may be attachedto the yarn holders and be wound thereon in a manner similar to thathereinbefore described below the place at which the ordinary bottoms ofthe yarn packages are to be formed in a manner similar in other respectsto that hereinbefore described.

Similarly yarn may be wound upon yarn holders of forms other than thoseshown.

This invention may be applied to ring doubling machines and to othermachines having yarn guiding means of other forms moved like ring railsin a manner similar to that in which it is applied in ring spinningmachines.
